The present invention relates to improvements in vapor electric lamps and the like. Heretofore lamps of the type referred to have been damaged in shipment and have 6 had their life shortened either by the vibrations and shocks incident to transportation or in the work laces which have caused the se aration of t e anode from its lead wire. Miiny attempts have been made to solve th1s 10 serious roblem, but all such efforts have increased the number of steps necessary to the production of the lamp, required abnormal sizes of materials, and consequently increased the cost thereof, without solving 16 the problem.

I have discovered that by providing the anode stem of a vapor device with a sleeve like member whose inner and outer edges or peripheries are in loose contact with the 20 wall of the lamp and with said stem, the lamps can be successfully shipped and used without the above defect making its appearance, and normal materials can be used in the fabrication of the lamp.

I have illustrated my invention in the accompanying drawings, in which;

Fig. l is a sectional elevation of the anode end of a vapor lamp showing the anode spacer in place;

Fig. 2 is a sectional plan view on line 22 of Fig. 1; and

Fig. 3 1s a perspective view of the anode spacer, in this instance of the fluted type.

Referring to the drawings, 1 is the anode end of the container of a vapor lamp and 2 is the anode sealed into the wall thereof, as shown at 3, 3. Prior to the sealing in Y of the anode 2 a spacing member 4 is slipped over the wires and rests on a shoulder 5 on the anode stem and thereafter said wires are sealed into the end of container 1, the spacer 4 being drawn up into proper position with respect to the wall of the container as shown in Fig. 1 during the sealing operation. The spacer 4 is in fluted form and serves in mercury containing devices. to break up and take up any mercury hammer action caused by the tilting ofthe container and thus protect the seal from being cracked by the hammer blow, and, further, at the same time rotect the anode from undue twisting an vibration from this same sense,

durable service.

I claim as my invention 2- 1. In combination in an electric device having an envelope and a conductor lead sealed into and extending in said envelope, means for supporting said lead against excessive bending within the envelope comprising a sleeve of refractory insulating material positioned about said lead and extending laterally into close proximity with the wall of said envelope, said electrode and the wall of said envelope serving to prevent any substantial longitudinal movement of said sleeve on said lead-in.

2. In combination in a mercury vapor discharge device having an envelope and an electrode therein with a lead therefrom sealed through the wall of said envelope and mercury in said envelope, means for sup porting said lead against excessive bending and for protecting the seal-in of the lead against mercury hammer during movement of the device comprising a sleeve. of refractory material positioned about said lead close to said seal-in and extending laterally into close proximity with the wall of said envelope.

3. In combination in a mercury vapor discharge device having an envelope containing a quantity of mercury, a lead sealed through the wall of said envelope, an electrode mounted on said lead in said envelope, means for supporting'said lead against excessive bending'and for protecting the sealin of thelead against mercury hammer comprising a sleeve of refractory material having portions extending across the envelope at said seal-in, said electrode and the wall of said envelope serving to prevent any substantial longitudinal movement of said sleeve on said lead-in.

4. In oombmation in a mercury vapor discharge device having an envelope contain g memes ing a quantity of mercury, a lead sealed across the envelope at said seal-in, said electhrough the Wall of said envelope, an electrode and the Wall of said envelope serving m trode mounted on said lead in said envelope, to prevent any substantial longitudinal means for supporting said lead against exmovement of said isleeve on said lead-in.
